- ~~No options for running without updates or auto update.~~
- ~~No filter to check only specific containers.~~
- ~~Faulty registry checkups stopped the updates completely.~~
- ~~No clear checks to skip containers producing errors.~~
- ~~Multi-digest images didn't correctly check with registry, giving false positives on updates.~~
### :hammer: Known issues
- No granular choice of what to update (except initial name filter).
- No detailed error feedback (just skip + list what's skipped) .
